[0049] The preparation method of described emulsified SBS modified asphalt comprises the following steps:

[0050] (1) add SBS, solvent naphtha in reactor, stir, obtain the SBS solution that concentration is 5wt%;

[0051] (2) After heating the petroleum asphalt to 120° C. for melting, then adding the SBS solution to it to obtain SBS modified asphalt;

[0052] (3) Heat the SBS modified asphalt to 138°C, mix and emulsify the heated SBS modified asphalt with 65°C anionic emulsifier, nonionic emulsifier and stabilizer, then add sodium hydroxide to adjust the pH 9, lower the temperature to 80°C to obtain emulsified modified asphalt; the emulsified SBS modified asphalt is composed of the following raw materials in parts by weight: 100 parts of 90# petroleum asphalt; 8 parts of SBS; 4 parts of stabilizer calcium chloride; 2 parts of sodium; 1 part of anionic emulsifier sodium dodecylbenzenesulfonate; 2 parts of nonionic emulsifier polyoxyethylene sorbitan monooleate; 80 parts of wa...

Description

technical field [0001] The invention relates to the field of water-emulsion asphalt waterproof coatings, in particular, the invention relates to a novel water-based asphalt coating composition and a preparation method thereof. Background technique [0002] Waterproof coatings are an important part of waterproof materials. According to the construction temperature, asphalt-based waterproof coatings in my country are divided into two categories: hot-melt construction type asphalt waterproof coatings and cold construction type waterproof coatings. Among them, the cold construction type is divided into solvent type asphalt waterproof coating and water emulsion type asphalt waterproof coating. The hot-melt asphalt waterproof coating is boiled on site, and the hot construction method produces a large amount of smoke, which is not only prone to fires and burns, but also has high energy consumption; solvent-based asphalt waterproof coatings have air pollution, are prone to poisoning...
